Patent number: 7629478Abstract: A process for preparing palm-based polyol monomer includes reacting unsaturated fatty acids or its corresponding triglycerides with polyhydric alcohol. In particular, one example uses oleic acid with about 70% purity as the starting material for preparing the polyol monomer. Moreover, another example uses refined, bleached, and deodorized (RBD) palm olein as an alternative to oleic acid as the starting material. The preparation of the polyol monomer involves the production of monoglyceride of unsaturated fatty acids, which was further epoxidized with peracid and finally ring opened with polyhydric alcohols. Such polyol monomer is used as a raw material for the production of various types of polyurethane products.Type: GrantFiled: November 6, 2006Date of Patent: December 8, 2009Assignee: Malaysian Palm Oil Board (MPOB)Inventors: Hoong Seng Soi, Nur Musyahadah Mazalan, Mohd Nurhisham Sattar, Tuan Noor Mazne Tuan Ismail, Hazimah Abu Hassan, Ooi Tian Lye, Salmiah Ahmad, Mohd Basri Wahid, Tan Sri Datuk Yusof Basiron
